面向 AI 开发者的 GPU Pod、Serverless 推理与集群云平台
按需、可中断或预留方式租用 GPU 实例，覆盖 30 多种 GPU 型号，从 RTX 4090 到 B200、B300 级别加速卡，部署于全球 31 个区域。
把任意容器部署为 API 端点，按需从 0 扩展到数千个 worker，仅为实际使用的算力付费。
启动多节点 GPU 集群用于分布式训练与大规模推理，可挂载共享存储，且无需长期承诺。
从精选中枢部署热门开源模型，或使用公共端点调用图像、音频和文本模型，无需自建基础设施。
在你自己的云中运行的持久化 AI 运行时
任务、追踪与制品可跨基础设施故障存活。运行可派生、恢复并从最后一个成功步骤重放，重试与缓存由运行时统一处理。
具名、带类型并带版本的制品把团队连接起来，血缘图清晰展示某个版本由哪次运行产出、又被哪些下游任务消费。
控制面托管在 Union 云，负载在你自己的 AWS、GCP、Azure 或新云集群上执行，始终处于自有安全边界内。
支持接入 OpenAI、Claude、PydanticAI、CrewAI 等智能体，每一轮都被追踪并在临时容器中沙箱执行，支持 MCP 服务器与人工审批。

由 PyTorch Lightning 创建团队打造的 AI 云平台
Combines serverless model APIs with on-demand GPU instances, offering a similar developer experience at competitive global price points.
FluidStack builds and operates large-scale compute infrastructure for AI, including gigawatt-class data centers and GPU clusters used for training and inference. The company designs its own power, cooling and data center systems, onshores manufacturing and deploys solar generation to supply the power its clusters need. Rather than a self-serve cloud console, FluidStack works with AI labs and enterprises to provision large reserved clusters, with orchestration tooling for the ML frameworks and schedulers those teams already use.
